I expected the DC offset to still show up after terminating the antenna input, but I don't understand how the spike always follows the signal unless something is actually there. >From your example, you have 435.300MHz as your center frequency which "appears" to have a large signal present. If you tune to 437.300MHz, do you see a strong signal at 435.300MHz still - or does it "follow" your center tuning to 437.300MHz and 435.300MHz is "in the noise floor"? > Thanks, > Naveen Brian _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
